Peter’S Anomaly

Abstract: Peter’s anomaly is a congenital corneal anomaly characterized by central or paracentral opacity. Around 60-80% of this anomaly is bilateral. We reported a girl of one year and six months as having bilateral corneal opacity since she was born. Diagnosis was based on ophthalmological examinations: the vision of the right and left eyes was ‘fix and follow the light’; sensoric nystagmus of both eyes; intra-ocular pressure of the right eye 37 mm Hg and of the left eye 40 mm Hg; corneal diameters of both eyes were 11 mm; 5-mm-central opacity of both cornea; both eye movements to all directions were normal; anterior chambers were shallow; iris was attached to the corneal endothelium; both lenses were difficult to be evaluated due to corneal opacity; fundal reflexes in both eyes were negative. The early medication given was thymolol 0.5% to decrease the intra-ocular pressure. If her health condition improved, a penetrating keratoplasty and a filtration surgery were recommended under general anaesthesia. Key words: Peter’s anomaly, corneal opacity, intraocular pressure, management.   Abstrak: Peter’s anomaly merupakan kelainan kongenital kornea yang ditandai dengan kekeruhan pada kornea bagian sentral ataupun parasentral. Sekitar 60-80% kasus Peter’s anomaly terjadi bilateral. Kami melaporkan kasus Peter’s Anomaly pada seorang anak berusia satu tahun enam bulan dengan kekeruhan pada kedua mata sejak lahir. Diagnosis ditegakkan berdasarkan pemeriksaan oftalmologis dimana didapatkan visus okuli dekstra dan sinistra fix and follow the light, nistagmus sensoris pada kedua mata, tekanan intra okuler pada mata kanan 37 mm Hg dan pada mata kiri 40 mmHg. Diameter kornea kedua mata 11 mm, adanya  kekeruhan pada sentral kornea (stroma) dengan diameter 5 mm pada kedua mata. Pergerakan  kedua mata ke semua arah normal. Bilik mata anterior dangkal, iris melekat pada endotel kornea, lensa kedua mata sukar dievaluasi oleh karena kekeruhan pada kornea. Refleks fundus negatif pada kedua mata. Penanganan awal yang diberikan berupa medikamentosa (timolol 0,5%) untuk menurunkan tekanan intra okuler sambil menunggu keadaan umum membaik untuk dilakukan penetrating keratoplasty and filtration surgery dibawah anastesi umum. Kata Kunci: Peter’s anomaly, kekeruhan kornea, tekanan intra okuler, penanganan.

Glaucoma is the leading cause of irreversible blindness, one of the risk factor recognised being high myopia. Intra ocular pressure may be normal in myopic patients, with optic nerve head glaucoma characteristics. Eye ball elongation and optic nerve head tilting may be present in patients with high myopia that will represent field defects mimicking glaucoma. Treating patients with myopia having suspected aspects of glaucoma may be a challenge but even more challenging is the diagnosis of glaucoma in myopic patients.: To evaluate the association of glaucoma features with myopia. To create the awareness regarding the long term follow up.: Patients in the age group of 15 to 45 years who had attended our institution over a period of one year who fulfilled the inclusion and exclusion criteria were subjected for this study. Fifty four patients who were diagnosed to have moderate or high degree myopia were selected for this analytical study. They were subjected to vision, ocular examination, tonometry and results obtained were analysed.: In our study moderate myopes constituted 55.5% and high myopes were 44.5%. The mean Intra ocular pressure and the mean corrected Intra ocular pressure in high myopes were observed to be higher than in moderate myopia. It was observed that higher prevalence of glaucoma was observed in high myopes.: There is a clinically as well as statistically significant difference between mean Intra ocular pressure and mean corrected Intra ocular pressure. So mean corrected Intra ocular pressure should be measured .From our study, there is a clear indication that there is increased prevalence of glaucoma in high myopes.

This Chapter focuses in the electrophysiological bases to support Trans Palpebral Electrical Stimulation TPES as a new alternative to control Intraocular Pressure IOP. Primary open Angle Glaucoma POAG is described in our approach as a dysfunction of the membrane potential of TM cells due to the dysfunction of the Maxi potassium depended Calcium Channels BKCa2+ of the Trabecular Mesh TM. We review through the paper the main contributions about Trabecular mesh dysfunction related with Voltage dependent ionic channels. We also present in this paper new results in controlling intra ocular pressure IOP during one year of trans palpebral Electric stimulation in patients with Primary open-angle glaucoma (POAG).

Objectives: To study the changes in intra ocular pressure (IOP) after phacoemulsification with intra ocular lens implantation. Study Design: Quasi experimental study. Setting: Lahore General Hospital, Lahore. Period: From 1-3-2017 to 30-9-2018. Material & Methods: The study was conducted after getting approval from ‘’Ethical Review Board’’ of Lahore General Hospital, Lahore. Patients presenting to the Eye OPD Lahore General Hospital were assessed for inclusion and exclusion criteria. All patients (n=) diagnosed with cataract significantly decreasing vision were selected. Patients having any coexisting ocular pathology i.e. corneal opacity, Glaucoma etc. were excluded from study. Pre operatively intraocular pressure was measured on slit lamp with the applanation tonometry. The patients were called for follow-up after at which time Visual acuity and intraocular pressure was again measured and findings recorded in the proforma. All the surgeries were performed by single surgeon. Results: Pre-operative mean intra ocular pressure was 22.02±1.403 mm Hg which reduced significantly to 20.39±1.363mm Hg, 19.61±1.418mm Hg, 18.94±1.738mm Hg after one day, one week and one month of surgery respectively. Conclusion: Phacoemulsification cataract surgery leads to a decrease in intraocular pressure.

Ocular Discharge

A 5-year-old Mongolian mare (Equus caballus Linnaeus, 1758) was observed to have corneal opacity and excessive ocular discharge. An ophthalmic examination revealed a moving thread-like cylindrical worm in the anterior chamber of the right eye. The parasite was successfully removed surgically. The worm was observed under light microscopy and confirmed as Setaria digitata by 12S rRNA gene amplification and sequencing. Phylogenetic analysis demonstrated similarity with Setaria digitata in the National Center for Biotechnology Information (NCBI) GenBank database isolated from other Asian countries. This report is the first confirmed case of equine ocular setariasis by molecular diagnosis in China, which may indicate its presence in livestock and promote research on its epidemiology.

Ocular Pressure

Glaucoma is one of the most common causes of blindness in the Western world and a major risk factor is increased intra-ocular pressure. We therefore used telemedicine in its control. Patients measured their intra-ocular pressure several times a day with a portable instrument and the values were then entered into a portable digital assistant. These data were transmitted by a modem to a central server. If the intra-ocular pressure was pathologically high, an email message was automatically sent to the ophthalmologist. The pressure curve, including a statistical analysis, was displayed in an easily readable chart format. Ten patients with glaucoma participated in a trial. Self-tonometry with telemedicine enabled continuous evaluation of the patient by the ophthalmologist. This approach offered the advantage of controlling the treatment remotely. Advantages for the patient were that the measurements were easily done at home under normal conditions, and the patient could control when the measurement and data transmission would be performed. Telemedicine is a cost-effective technique enabling the early diagnosis of pathologically increased intra-ocular pressure.
