Excimer laser vision correction among ophthalmologists in Saudi is much higher than the market penetration in the general population reported in other countries. Most of the ophthalmologists who underwent the procedure were satisfied with the outcome.
All people with oculocutaneous albinism (OCA) have reduced vision. This study aimed to assess the benefits of low vision aids for people with OCA.
Seventy-seven consecutive people with OCA age 4 years and above examined in a low vision clinic were included in the study. Uncorrected and best-corrected visual acuity (VA), VA with low vision devices, types of low vision aids, and refractive errors data were analyzed.
Of the 77 people with OCA, 57% were in the age group between 4 and 15 years and 43% in the age group of 16 years and above. At the time of presentation, the percentages of visually impaired, severe visually impaired, and blind (using WHO low vision criteria) were 52%, 22%, and 25%. Among them, 39% has near VA of 1 M or better. Difference in the means of the spherical equivalent refractive error in the right eyes and left eyes was -0.494 diopters (-01.686, 0.699; 95% confidence interval). VA improved significantly after adequate refractive correction by more than one log MAR lines in 38.6% (
< 0.01). With low vision devices, in 85.7% (
= 66) participants, VA was enhanced to normal level (6/18 or better) in the better eye while 7.8% still remained in the blind category. Telescopes were prescribed to 61% people for the enhancement of distance VA and hand hold magnifiers were prescribed to 22% people to meet their needs.
Low vision aids can be successfully used in visual rehabilitation of people with OCA to meet their needs.

The study aims to evaluate and see if experiential learning theory for teaching cataract surgery can improve the ability of students to retain more knowledge compared to the classical or traditional way of teaching.
A pre and post control group design of 32 graduates was conducted in 2016 at King Saud University, Riyadh, Saudi Arabia to examine the effect of experiential learning as an applicable way for teaching cataract surgery. The total of graduates including males and females were divided into control and experimental groups to which the educational materials about cataract surgery were presented as a lecture and as wet lab session respectively. All the data collected were entered in SPSS version 22 for analysis and a
≤ 0.05 was considered significant.
Both control and experimental groups showed good retention rate of knowledge. However, the gain of knowledge was more in the Wet lab group. https://www.selleckchem.com/products/nms-p937-nms1286937.html The scores mean increased more than 5 points in this group compared to 2.5 points only in the lecture groups.
Both teaching modalities were effective in improving the knowledge rate of the students. However, in the experiential learning group (Wet lab group), the gain of knowledge was higher compared to that in the traditional group (lecture group).

To report the epidemiological data, clinical profile, management, and outcomes of canalicular lacerations in the pediatric age group in a tertiary eye care hospital in Saudi Arabia.
This retrospective study evaluated pediatric patients who underwent canalicular laceration repair in the last 15 years at King Khalid Eye Specialist Hospital (KKESH), Saudi Arabia. Demographics, causes of injury, type of trauma, surgical approach, and outcomes were analyzed. The success of repair was defined as the absence of epiphora after canaliculus repair with negative dye disappearance test (DDT). Success within subgroups was compared.
< 0.05 was considered statistically significant.
The study sample was comprised of 43 patients, with a median age of 6.35 years (range, 1.77-17.96 years). Most of the patients were males (69.8%). Sharp objects were the most common cause of canalicular laceration (46.5%), being 9 (20.9 %) caused by a metallic clothing hanger. Lower canaliculus was involved in 65.1%, upper canaliculus in 32.6%, and both canaliculi in 2.3% of patients. Canaliculus repair was performed with a bicanalicular stent in 58.1 % and monocanalicular stent in 41.9 % of patients.The success rate and risk of complications using bicanalicular or monocanalicular stent did not differ (
= 0.065). Functional success was achieved in 87.5% of patients.
Canalicular laceration is common in male children, mainly affecting the lower canaliculus. There was no difference in success rate between monocanalicular and bicanalicular stent. As canalicular laceration could be related to social determinants, the main causes should be highlighted in community health education initiatives.

The purpose was to determine the minimum near-addition power needed using Proclear
multifocal D-Design contact lens (adds +1.50 D, +2.50 D, +3.00 D, and +3.50 D) to invert the pattern of relative hyperopic defocus in the peripheral retina into relative myopic defocus among the eyes of myopic schoolchildren.
Twenty-seven right eyes (24 females and 3 males) of 27 myopic schoolchildren aged between 13 and 15 years were included in this study. The measurements of central refraction, peripheral refraction (between 35° temporal and 35° nasal visual field in 5° steps), and lag of accommodation were conducted using the Grand-Seiko WR-5100K open-field autorefractometer initially without correction (WC), followed by with correction using four different addition powers of Proclear
multifocal D-Design contact lens in random sequence. Axial length was measured using a handheld probe ultrasound A-scan (Tomey AL-2000).
The relative peripheral refractive error showed high hyperopic defocus of +1.08 ± 1.24 D at 35° nasal and +1.
