Cardinal Feature

Glaucoma is a chronic disease condition prevalent globally leading to blindness. It results in optic neuropathy which is very difficult to manage. An increase in intraocular pressure is a cardinal feature in most cases. This study aims at lowering the intraocular pressure by leech therapy, which is a conventional treatment method described in Ayur- veda. Leech therapy was conducted in the selected patients and intraocular pressure before and after treatment were recorded. The study showed clinically and statistically significant changes in the intraocular pressure. Keywords: Leech therapy, glaucoma, intraocular pressure

Purpose:  To determine the Anterior Chamber depth and Intraocular pressure change following uncomplicated phacoemulsification. Study Design:  Quasi experimental study. Place and Duration of Study:  Layyton Rehmatullah Benevolent Trust Free Eye and Cancer Hospital, Lahore from 16/12/2017 to 15/06/2018. Methods:  One hundred and thirty nine patients who came to Layyton Rehmatullah Benevolent Trust Free Eye for phacoemulsification and IOL implantation were included in the study. Anterior Chamber depth was measured with IOL Master and intraocular pressure was determined using Goldmann Applanation Tonometer one day before and one month after surgery. Data was recorded on a self-designed proforma. Comparison between pre- and post-operative data with respect to change was analyzed by chi-square test. P-value ≤ 0.05 was considered significant. Results:  The mean intra-ocular pressure dropped from 14.36 ± 4.19 mmHg to 12.14 ± 4.26 mmHg 1 month after surgery with a mean drop of 2.21 ± 0.65 mmHg while the mean anterior chamber depth increased from 2.31 ± 0.08 mm to 3.59 ± 0.37 mm with a mean increase of 1.29 ± 0.36 mm. There was no statistically significant difference in the mean change of intra-ocular pressure and anterior chamber depth across various subgroups based on patient’s age, gender and duration of cataract. Conclusion:  Phacoemulsification and IOL implantation not only improves the visual acuity by removing the cataract but also deepens the anterior chamber and decreases intra-ocular pressure, which can have a beneficial effect in glaucoma patients.

Purpose: Cataract surgeries have been shown to reduce intraocular pressure. We used a Sensimed Triggerfish® contact lens sensor to compare intraocular pressure levels and their fluctuation between before and after cataract surgeries in patients with normal-tension glaucoma. Methods: This was a prospective open-label study. Thirteen patients with normal-tension glaucoma were included. All patients underwent a 1-month washout and discontinued glaucoma medications during this study. In each eye, intraocular pressure fluctuations over 24 h were measured with the contact lens sensor before and at 3 months after the cataract surgery. We compared intraocular pressure levels and their fluctuation between before and after cataract surgeries. We used two approaches to evaluate the amplitude of intraocular pressure fluctuations: dual-harmonic regression analysis, and measurement of the difference between the maximum and the minimum value. Results: The mean pre-operative intraocular pressure was 14.7 ± 2.2 mm Hg and mean post-operative intraocular pressure was 11.4 ± 2.2 mm Hg. Cataract surgery significantly decreased intraocular pressure (p = 0.0005). In both methods, the post-operative fluctuations in intraocular pressure over 24 h were significantly smaller than their pre-operative counterparts (dual-harmonic regression analysis: p = 0.0171; difference between the maximum and the minimum: p = 0.0398). Conclusion: Cataract surgery decreased both intraocular pressure values and intraocular pressure fluctuations in normal-tension glaucoma patients.

Aim: To determine changes in intraocular pressures (IOP) associated with drugs used for general anesthesia (GA) induction in eye surgery. Study design: Observational prospective study Place and duration of study: Department of Ophthalmology, CMH Rawalpindi from 1st March 2015 to 31st May 2016. Methodology: Eighty subjects that were advised to undergone various ophthalmic surgical procedures under GA were included in the study. Visual acuity, intraocular pressure (IOP), extra ocular motility, anterior and dilated posterior segment examination were carried out to determine the ophthalmic status. Mixed anesthetics were used in all patients. IOP was recorded at T1 (10 min before induction of anesthesia), T2 (10 min after intubation), and T3 (at the conclusion of surgery before extudation) using Perkins tonometers. Changes in IOP before induction of GA, after intubation, and just before extubation were recorded. Results: Mean pre-anesthesia IOP for patients of age was 42.3 years with a range of 9-70 years and mean IOP was 16.4 with a range of 10-23 mmHg. There was a significant decrease in the mean IOP at T2 (Perkins: 4-6 mmHg) and T3 (Perkins: 5-8mmHg) as compared to the IOP at T1 (10-18mmHg. The decreases in IOPs at T2 and T3 were similar in both anesthetic groups (T2: P=4-6mmHg; T3: P = 5-8 mmHg). Conclusion: Significant decrease in IOP after GA was observed with mixed anesthetic agents. For management decisions this aspect of general anaesthesia drugs on IOP as noted with currently used anesthetic agents has to be accounted for and decisions are taken accordingly.

Objective: This study sets out to determine if there is any statistical difference in the results of measuring intraocular pressure (IOP) uncorrected for Central Corneal Thickness with Air Puff Tonometry and corrected with pachymetry for clients undergoing screening for glaucoma at the department of Ophthalmology, University of Port Harcourt Teaching Hospital (UPTH), Nigeria. Methods: One hundred and thirty-two (132) adults were screened for glaucoma during the 2019 World Glaucoma week in UPTH Port Harcourt, they had their IOPs measured with Air Puff (Non-contact) Tonometer (Pulsair intelliPuff Tonometer, Keeler), after which they underwent pachymetry (Sonomed Escalon PacScan Plus) to determine corneal thickness after which the corrected IOP was determined by using a correction factor for adjusting IOP based on corneal thickness [1].  The results were analyzed using SPSS version 20 to determine statistical differences. Results: There was a statistically significant difference between intraocular pressure (IOP) measurements when corrected with pachymetry than when it is uncorrected. In our study the mean uncorrected IOP RE and LE was 14.53 mmHg and14.75 mmHg respectively while Corrected IOP RE and LE was 16.37 mmHg and 16.72 mmHg respectively. Conclusion: Intra ocular pressure measurement adjusted with pachymetry for corneal thickness may be a better option for tonometry and we propose this be considered during intra ocular pressure measurement.

Introduction: The ideal optical properties of the eye requires support of state of the eye-ball which is normally regulated by the intraocular pressure (IOP). There is variation in the measurements of IOP with Goldmann applanation tonometry if the thickness of the central cornea is not uniform, the IOP is high when cornea is thicker and vice versa. Therefore, the central corneal thickness (CCT) is thought to affect the IOP readings, however, as shown, the evidence available remains controversial. The aim of the study was to determine correlation between CCT and IOP. Objectives: To determine the correlation between the Central Corneal Thickness (CCT) and Intra Ocular Pressure (IOP). Study Design: A cross-sectional study. Placeand Duration: Department of Ophthalmology, Aga Khan University Hospital, Karachi from July to December, 2014. Methodology: During the study period of six months total 431 participants were purposively sampled according to the set criteria. Variables included were age, gender, CCT, and IOP. Correlation between IOP and CCT was assessed by using Pearson correlation test, P value of < 0.05 was considered significant. Results: Out of 431 participants, 239 (55.5%) males and 192 (44.5%) females. The mean age was 34.9 ranging from 20 to 50 years. The mean central corneal thickness of right eye was 529 μm with SD ± 39.5 and range of 473-591 μm. The mean intraocular pressure of right eye was 14.7 μm, SD ± 3.1 with a range of 9-21 mmHg. The left eye mean central corneal thickness was 533, SD ± 29.6 with range of 481-589 μm. The mean intraocular pressure of left eye was 15.6, SD ± 3.1 with a range of 10-21 mmHg. Strong positive correlation was found (P-value < 0.001) between central corneal thickness andintra ocular pressure for both eyes. Conclusion: There is positive correlation between CCT and IOP. Therefore, along with the routine ophthalmic examination for intraocular pressure measurements pachymetry should also be considered for accurate interpretation of the results.

In four patients with chronic paroxysmal hemicrania, two of whom could precipitate attacks mechanically, various autonomic function tests were carried out in connection with attacks. Not all features could be studied in all patients, Forehead sweating and temperature were measured. Sweating, tearing, and nasal secretion were studied after systemic atropine administration, which reduced attack-related sweating, tearing, and nasal secretion markedly. Intra-ocular pressure was measured before and after the topical administration of an alpha-receptor blocking agent, thymoxamine. After topical thymoxamine no definite intra-ocular pressure increase occurred during precipitated attacks. In attacks precipitated by head movements, forehead sweating occurred seconds (up to 30 sec) before the pain. This study indicates that at least in some CPH cases, forehead sweating is not caused by the pain. Nor is the pain secondary to increase in intra-ocular pressure. The thymoxamine experiments seem to indicate that alpha-receptors in some way may be connected with the intra-ocular pressure increase during attack.

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.
