Retinoscopy

Retinoscopy is a non-invasive technique used to measure the refractive error of the eye.
It involves shining a beam of light into the eye and observing the reflected light, which can be used to determine the eye's focusing power.
This method is commonly used in optometry and ophthalmology to diagnose and correct vision problems, such as nearsightedness, farsightedness, and astigmatism.
Retinoscopy is a reliable and accurate way to assess refractive error, and is often used as a starting point for prescribing corrective lenses.
By understanding the principles and best practices of retinoscopy, researchers can enhance the reproducibility and accuracy of their vision research, leading to more reliable and impactful findings.

Performance Evaluation of Assays

The evaluations were conducted according to the WHO pre-qualification protocol for performance evaluation. All personnel working on the evaluations were trained in performing and/or interpreting the assays. The results, recorded on standardized data collection sheets, were visually interpreted by the performer of the assay and independently by two other readers. Data entry into the standardized excel files was checked by a second person by visually comparing a print-out of the entered data with the raw data.
All specimens were tested in singular (initial testing). Specimens from the WHO specimen reference panel with indeterminate results (very faint doubtful shadow on the test line or discrepancies between the three readers) or results discrepant from the reference result were repeated in duplicate with the same lot (repeat testing) and (if possible) with the other lot. The result that occurred the most (at least two out of three) was recorded as the final result.
Results obtained with the assays under evaluation were compared to the results of the reference testing algorithm for HIV and Syphilis (described below).

Visual Acuity Measurement in Pediatric Ophthalmology

In the clinic, a detailed parental interview was conducted, including questions regarding family income and preschool or daycare enrollment.11 (link) The examination, described in detail elsewhere,11 (link),12 (link) included VA testing, evaluation of ocular alignment, cycloplegic refractive error measurement, and anterior segment and dilated fundus evaluations. Cycloplegic refraction was performed with the Retinomax Autorefractor (Right Manufacturing, Virginia Beach, VA) at least 30 minutes after instilling the second of 2 drops of 1% cyclopentolate given 5 minutes apart. Cycloplegic retinoscopy was performed if Retinomax readings with confidence ratings of ≥8 were not obtained in both eyes after 3 attempts per eye. If parents refused cycloplegic eyedrops, non-cycloplegic retinoscopy was performed.
Presenting monocular distance VA measurement was attempted using an electronic visual acuity (EVA) tester6 (link) with the ATS protocol.5 (link) The EVA system uses a handheld device programmed with the protocol algorithm to control the presentation of high-contrast black-and-white single HOTV optotypes framed by crowding bars spaced a half-letter width from the letter on a 17-inch monitor. The ATS testing algorithm has been described previously;5 (link),6 (link) an initial screening phase obtaining an approximate VA threshold is followed by a first threshold determination phase, a reinforcement phase, and a second threshold determination phase. The VA score, measured in 0.1 logMAR increments from 20/800 to 20/16, is the smallest logMAR level passed in either of the two threshold phases.
The VA testing protocol specific to MEPEDS has been reported in detail.3 (link) Children were seated 3 meters from the monitor with a lap card containing the single-surround HOTV letters. Children who had difficulty comprehending the task underwent a binocular pretest at near, which if passed was followed by a binocular pretest at 3 meters, and monocular threshold testing for those able to complete the pretests. Children were instructed to identify the letter on the monitor verbally or by pointing to the matching optotype on the hand-held card; those who knew their letters were still encouraged to refer to the card. The right eye was tested first, followed by the left, with the fellow eye occluded with an adhesive patch or, rarely, occluding glasses. Testing was attempted on all children, including those with developmental delay or disability.

Macular Thickness and Volume in Healthy Eyes

This cross-sectional, quantitative, and hospital-based study comprised 126 eyes of 28 male and 35 female subjects (mean age, 21.17±6.72 years; age range, 10–37 years). They were recruited between February and December 2013 from the Department of Ophthalmology, Institute of Medicine in Nepal. Ethical clearance approval was obtained from the Institutional Review Board at the Institute of Medicine. The study fully adhered to the tenets of the Declaration of Helsinki. Before their inclusion, informed verbal consent was sought from the subjects who were 18 years or over and from the parents or attendants when the subjects were under 18 years. Sixty-three subjects (126 eyes) diagnosed as having healthy normal eyes following a complete anterior and posterior segment evaluation and refraction, and not having diseases and conditions (diabetes mellitus; hypertension; transplant; autoimmune disease; high intraocular pressure, ie, greater than 21 mmHg; and refractive error, ie, greater than ±0.25 D spherical equivalent) underwent a fast mode macular scanning with the commercially available spectral domain (SD) OCT (Spectra lis HRA + OCT; Heidelberg Engineering, Inc., Heidelberg, Germany) immediately after retinoscopy was carried out by an optometrist when the pupils were still dilated (>5 mm diameter). The basic working principles have already been explained in great detail.6 (link),7 (link) The scan was performed over a 6×6 mm² area in the posterior pole to achieve a high quality image. The subjects were asked to focus on the target. The center point of each scan direction represented minimum foveal thickness (central minimum thickness, or foveola).8 (link) A traditional Early Treatment Diabetic Retinopathy Study (ETDRS) grid which contains three concentric rings of diameters 1, 3, and 6 mm, and two reticules to divide the macula into nine sections was employed. Scanning results were then analyzed by using the OCT Version 5.6.4 software. Any obscure images and artifacts were not considered. Axial length measurements were taken using an ultrasound A-scan biometer (Axis-II PR; Quantel Medical, Inc., Clermont-Ferrand, France).
Central subfield thickness (CST), also known as foveal thickness, was defined as the average thickness of the macula in the central 1 mm ETDRS grid.9 (link),10 (link) Average macular thickness was defined as the mean of thicknesses in nine sections.11 Macular volume was defined as the sum of all volumes of all nine sections. The grid is shown in Figure 1.

Sphero-Cylindrical Refraction in Children with SBA-RS

This prospective study is covered by Institutional Review Board at Providence Hospital with Clinical Trial Registry (NCT03668067) and de-identified data access from www.ABCD-Vision.org. The study complies with HIPAA and the Declaration of Helsinki. Images and video of children examined by this technique are included. Written parental informed consent with appropriate translation was obtained.
The SBA-RS rack (Eye Care and Cure: 22 cm × 6 cm × 0.5 cm) has one row of convex (plus) lenses from 1 to 10 diopters arranged continuously so extra plus lens can be placed horizontally over the nonretinoscoped eye to achieve fogging. The rack appears like a yellow school bus with a millimeter ruler (Figure 1). One “wheel” has a −5 concave lens and the other a translucent occluder.
The retinoscopy technique presented the previously hidden school bus as a surprise (brought forward from a back pocket) and handed to the child asking if any older siblings ride a bus. Then, sitting behind the windows was demonstrated by the retinoscopist gently transferring the bus toward the child’s eye covering the nonscoped eye with adjacent, higher plus “windows.” The desired response was more “with” retinoscopy reflex 1–3 seconds looking through the skiascopy lens, and sliding the bus back and forth toward higher plus lenses watching for more “with” reflex and mydriasis accompany-relaxed accommodation. Neutralization required confirmation of astigmatism power and axis for the first eye. Then, the “bus” was reversed “to come home from school.” Often accommodation was already relaxed for the second eye as soon as the reversed-direction bus was in place (Supplementary video).
Since SBA-RS has just one row of integer-value plus spherical lenses, retinoscopy made liberal use of 1) adjusting the working distance to determine fractional refractive values for sphere and cylinder power and 2) sliding the bus back and forth to relax more accommodation uncovering more hyperopia. For higher myopic patients, the concave −5 lens in one of the “bus wheels” was utilized. Utilizing this simple device, the single −5 lens and the +1 through +10 convex lenses, sphero-cylinder refraction could be determined with a range from −10D to +8.5D. For the extremely high hyperopic patients, the SBA-RS was checked by holding an additional +12 lens to allow fogging when refracting through the +10 lens.
Patients undergoing initial or follow-up comprehensive ophthalmic examination were screened with SBA-RS before retinoscopy with our “gold-standard” cycloplegia at least 20 mins following instillation of cyclopentolate 1%. For objective comparison, many of the patients also had Retinomax automated refraction before cycloplegic refraction. Data were collected regarding age, indication for examination and neurodevelopmental delay such as autism, syndrome, attention-deficit hyperactivity disorder (ADHD), fetal alcohol syndrome (FAS), etc. The clinician performing the cycloplegic examination mainly used phoropter with refinement and was usually not aware of the Retinomax findings at the time of the refraction.
Refractive values were organized to afford the best comparison. Spherical equivalent was sphere plus 0.5× cylinder power in plus format. Power vectors for astigmatism (J0 Horizontal Jackson-Cross and J45 oblique Jackson-Cross) were calculated by (J₀) = [−(K_steep−K_flat)/2] × cos2α and (J₀) = [−(K_steep−K_flat)/2] × cos2α where K represents cylinder power and alpha (α) the axis in radians.18 (link) We classified cases of hyperopia as those whose cycloplegic spherical equivalent exceeded 0.7 diopters and those with astigmatism as those whose plus cylinder power exceeded 0.7 diopters. Bland-Altman analysis and interclass correlation coefficient (ICC) were determined for these refractive values.
Correlations were assessed by linear regression with Spearman product moment coefficient. Medians between groups were compared with Mann–Whitney test. Proportions were compared with Chi-square test. A probability of 0.05 was considered significant.
Sample size calculation for linear regression with 2 predictors: statistical power level 0.9, probability level 0.01, and the anticipated effect size of 0.05 indicate a minimal sample size of 351.

Comprehensive Ocular Measurement Protocol

The axial length was measured with an IOL Master (Carl Zeiss Meditec, Inc., Dublin, CA, USA). After that, the refractive error of the participant was determined through an autorefractor followed by retinoscopy and subjective sphero-cylindrical refraction to obtain the maximum positive, which also ensured the best visual acuity. Best corrected visual acuity (BCVA) was measured with the ETDRS high-contrast chart (105 cd/m²) under photopic conditions (150 lux) measured with the Luminance Meter LS110 and Illuminance Meter T10 (Konica Minolta Sensing, Inc., Osaka, Japan), respectively. The interpupillary distance was obtained with the Pupilometer HX-400 (Chongqing Yeasn Science and Technology Co., Chongqing, China). The measurements for the control condition were obtained with the participant fully corrected in the trial frame. These measurements included peripheral refraction, contrast sensitivity, and light disturbance analysis. Thereafter, these measurements were repeated with the perifocal lenses.

Comprehensive Ocular Biometric Evaluation

The participants underwent cycloplegic autorefraction and traditional refraction using retinoscopy and then subjective refraction with fogging was performed. Fogging refers to using plus powers to bring the optical point of focus in front of the retina to ensure that accommodation is adequately relaxed. The principle of fogging involves using spherical powers to create artificial myopia, thereby moving the entire area of focus in the eye in front of the retina to create a situation where an attempt at accommodating will blur the vision, which further causes the patient to relax accommodation. Fogging is effective irrespective of the inherent refractive state of the eye and the efficacy of fogging in refraction has been demonstrated [16 (link)].
Corneal tomography, analysis of the anterior segment, and measurement of axial length using the Pentacam AXL^® device were then carried out. The variables studied were maximum and minimum keratometry, anterior chamber depth (ACD), corneal horizontal diameter (WTW), central corneal thickness, corneal asphericity (Q), and axial length (AXL). The mean keratometry (Km) was calculated as the average of K1 and K2 within the 3-mm central optical zone for statistical analysis. A flowchart of the design of the study is presented in Figure 1.
Each measurement was taken three times in succession by the same experienced examiner under standardized conditions to minimize error. The tomographic and biometric measurements were considered optimal when the quality factor was greater than 95% according to the manufacturer’s software instructions.

Unilateral Congenital Ptosis Treated with PTFE Frontalis Suspension

This was a retrospective review that approved by the Ethics Committee of the Hunan Children’s Hospital (KS2015–48) and all subjects provided written informed consent.
We prospectively examined the medical records of all patients, younger than 2 years, who underwent frontalis suspension surgery with PTFE to address a severe unilateral congenital ptosis. Between January of 2016 and December of 2017, we recruited 53 Chinese patients with severe unilateral congenital ptosis, and excluded those presenting with ptosis secondary to systemic diseases or other eyelid diseases. Patient data including age, sex, time of operation, margin reflex distance, astigmatism degree and type measured with refractive examination under atropine was recorded pre- and postoperatively. Postoperative complications were also described. Surgical indications were unilateral congenital ptosis that was severe enough to cover the 50% of the pupil and possibly cause amblyopia. Each patient underwent follow-up examinations for more than 1 year after surgery, and were photographed regularly.
Routine ophthalmic examinations were performed in all patients. Levator and frontalis muscles function was unavailable because the patients were uncooperative. Cycloplegic refraction was measured after administrating 1% Atropine eye gel, thrice per day for 3 days. All procedures were performed using a handheld retinoscopy by optometrist preoperatively and 1 month, 6 months, and 1 year postoperatively. We used the minus cylinder to express all refraction measurements for consistency. We used the standard definition of astigmatism referred by Griepentrog [7 (link)]. Preoperative refraction was checked in all patients to compare the astigmatism status between ptotic and fellow eyes. During the follow-up, the patients also underwent a refractive examination to assess the differences of astigmatism in the ptotic and fellow eyes before and after surgery. Since the refractive data 1 year after the surgery of certain patients was missing due to an absence of follow-up data, we included and analyzed the refractive data of only 39 patients.
Each procedure was performed by two operators with general anesthesia. We used the frontalis suspension of the double rhomboid approach [8 (link)] with PTFE. Surgical success was defined by the presence of an acceptable eyelid position and height. Recurrence was defined as the eyelid covering the visual axis again after surgery. We documented the eyelid position using the photo taken at every follow-up. Kaplan-Meier survival analysis was performed with the failure time being measured as the time from initial surgery until disease recurrence. We also recorded the complications for each case.
Statistical analysis was performed using software Prism 5.0 (Graphpad Software, San Diego, CA, USA). Statistical significance was considered at P < 0.05. All data are expressed as the mean ± standard deviation. Paired t-test was used to compare the astigmatism between fellow and ptotic eyes before surgery. Chi-square test was used to compare the frequency of severe astigmatism (≤ − 1.50 DC) and astigmatism type between fellow and ptotic eyes before surgery. One-way ANOVA was used to compare the astigmatism degree before and after surgery in both ptotic and fellow eyes. Kaplan-Meier analysis was used to estimate surgical failure, defined as the eyelid covering the visual axis postoperatively.

More about "Retinoscopy"

Retinoscopy, also known as skiascopy or shadow test, is a non-invasive technique used to measure the refractive error of the eye.
This method involves shining a beam of light into the eye and observing the reflected light, which can be used to determine the eye's focusing power.
Retinoscopy is commonly used in optometry and ophthalmology to diagnose and correct vision problems, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
The IOL Master, OPD-Scan III, IOLMaster 500, and Pentacam are some of the advanced instruments used in conjunction with retinoscopy to provide a comprehensive assessment of the eye's optical properties.
These tools can measure parameters like corneal curvature, anterior chamber depth, and lens thickness, which are crucial for accurately determining the appropriate corrective lenses.
Cyclopentolate hydrochloride is a commonly used eye drop that can be employed during retinoscopy to temporarily paralyze the eye's ability to focus, known as cycloplegia.
This allows for a more accurate measurement of the eye's refractive error.
The Canon Autorefractor RK-F1 and Pentacam HR are examples of automated retinoscopy devices that can provide objective and reproducible measurements of refractive error.
These instruments can enhance the accuracy and efficiency of the retinoscopy process, making it a valuable tool for both clinicians and researchers.
