Fulltext Eyelid hook injury - A preventable domestic injury

Omar N, Salleh R

Saudi J Ophthalmol, 2009 Oct;23(3-4):219-20.
PMID: 23960864 DOI: 10.1016/j.sjopt.2009.10.007

The aim of this report is to describe the presentation and management of eyelid injury resulting from the hook of a rubber string. A seven-year-old boy presented with pain of the right upper eyelid. A rubber string with metal hook ends, snatched his right eye from below. The hook pierced through his upper eyelid from the conjunctival surface and remained in situ. However, there was no globe laceration noted. Removal was performed by reverse-tracking of the hook through the wound. The wound was stitched with 6'0 Vicryl sutures. Healing was excellent with minimal scarring.
Fulltext A case of choroidal melanocytoma mimicking a choroidal melanoma

Ahmad SS, Lad L, Ghani SA

Saudi J Ophthalmol, 2015 Jul-Sep;29(3):242-5.
PMID: 26155089 DOI: 10.1016/j.sjopt.2015.02.002

A 17-year-old young girl was seen by us with complaints of progressive, painless decreasing vision in one eye for the last 4 years. No other supporting history could be elucidated. On examination, a large choroidal mass was found. Since the features were suggestive of malignant melanoma of the choroid, an enucleation of the eye was performed. Subsequently, histopathological examination of the enucleated eye revealed findings consistent with melanocytoma of the choroid. This case is unique in that the patient was of relatively young age and the tumor was huge compared to previous such reports.
Inverting peripheral hyperopic defocus into myopic defocus among myopic schoolchildren using addition power of multifocal contact lens

Allinjawi K, Kaur S, Akhir SM, Mutalib HA

Saudi J Ophthalmol, 2020 12 28;34(2):94-100.
PMID: 33575529 DOI: 10.4103/1319-4534.305035

PURPOSE: 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.
METHODS: 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).
RESULTS: The relative peripheral refractive error showed high hyperopic defocus of +1.08 ± 1.24 D at 35° nasal and +1.06 ± 1.06 D at 35° temporal visual field WC. All Proclear multifocal contact lenses (MFCLs) decreased the peripheral hyperopic defocus with increasing addition powers (F [2.938, 47.001] = 13.317, P < 0.001). However, only +3.00 D addition and +3.50 D addition (P = 0.001) could invert the peripheral hyperopic defocus into peripheral myopic defocus. Apart from that, the +3.00 D addition lens showed the lowest lag of accommodation (+1.10 ± 0.83 D) among the other MFCL adds (P = 0.002).
CONCLUSION: A +3.00 D addition Proclear MFCL is the optimal addition power that can invert the pattern of peripheral hyperopic defocus into myopic defocus.
Fulltext An introduction to DARC technology

Ahmad SS

Saudi J Ophthalmol, 2017 Jan-Mar;31(1):38-41.

Glaucoma is a multi-factorial neurodegenerative disorder. The common denominator in all types of glaucomas is retinal ganglion cell death through apoptosis. However, this cellular demise in glaucoma is detected late by structural or functional analyses. There can be a 10-year delay prior to the appearance of visual field defects and pre-perimetric glaucoma is an issue still being addressed. However, a new cutting-edge technology called detection of apoptosing retinal cells (DARC) is being developed. This technique is capable of non-invasive, real-time visualization of apoptotic changes at the cellular level. It can detect glaucomatous cell damage at a very early stage, at the moment apoptosis starts, and thus management can be initiated even prior to development of visual field changes. In future, this technique will also be able to provide conclusive evidence of the effectiveness of treatment protocol and the need for any modifications which may be required. This article aims to provide a concise review of DARC technology.
Fulltext Water related ocular diseases

Ahmad SS

Saudi J Ophthalmol, 2018;32(3):227-233.

A number of ocular diseases can be attributed to contaminated water and we have coined a term "Water-related ocular diseases (WRODs)" to denote this wide-spectrum of conditions. WRODs are directly related to human contact with water and can occur through toxic, allergic, inflammatory or infective mechanisms. The non-infective causes can include chemicals used to clean swimming pools, oil spills and water-sport related injuries. Similarly, a number of infective organisms causing ocular diseases are transmitted through water. Since, these conditions can occasionally prove devastating, a review was done with the following aims: (i) To study the epidemiology of WRODs (ii) To assess the clinical presentation and current management of WRODs (iii) To highlight the future challenges and possible solutions to these problems. The online search was conducted utilizing search engines such as PubMed, Google Scholar, ClinicalKey and the Virtual Library of the Ministry of Health, Malaysia for relevant terms such as water-borne, swimming pool and eye infections.
