“…Because the location of IOP measurement influences the result, with IOP being the greatest in the inferotemporal region of the sclera, a further study is recommended measuring tpIOP at different locations around the limbus after TPRK. [ 3 ]…”

“…The steps to measure IOP in healthy adults using a Diaton tonometer are described in detail by Da Silva and Lira. [ 3 ] The patient was asked to look down so that the probe would be located at the superior region of the sclera above the limbus. Central corneal thickness (CCT) and corneal epithelial thickness were measured with the help of anterior optical coherent tomography (Pentacam AXL, Oculus, Germany).…”

PURPOSE: To present changes in transpalpebral intraocular pressure (tpIOP) in eyes after transepithelial photorefractive keratectomy (TPRK) in myopic Saudi patients and its determinants. METHODS: This one-armed cohort included the myopic eyes of Saudi adolescents treated with TPRK in 2020–2021. The difference in tpIOP before surgery, 1 week after surgery, and 1 month after surgery using Diaton was the main outcome. Central corneal thickness (CCT), myopia grade, gender, age, and corneal epithelial thickness before surgery were independent factors. Matched-pair analysis was conducted. The determinants of tpIOP post-TPRK were studied. RESULTS: Our cohort included 193 eyes of 97 participants (25.6 ± 5.8 years). Mild, moderate, and severe myopia were present in 93, 79, and 21 eyes, respectively. tpIOP was 22 mmHg or more in 5 and 8 eyes at 1-week and 1-month follow-up, respectively. The change in tpIOP ranged from − 7.00 to + 11.0 mmHg at 1 week and − 8.0 to + 26.0 mmHg at 1 month. The median change of CCT at 1 month was 59 μ. Change in tpIOP was not correlated with change in CCT at 1 month ( r = −0.107, Pearson P = 0.14). Change of tpIOP was significantly correlated to spherical equivalent (SE) before surgery (matched-pair P < 0.001). SE (Mann–Whitney U P = 0.02) and tpIOP (Mann–Whitney U P = 0.02) before TPRK were significantly correlated to tpIOP >22 mmHg after TPRK. CONCLUSION: The changes in tpIOP following refractive surgery correlate to the refractive status of the eye and tpIOP before surgery.

“… 1 , 2 , 3 Different methods and devices including modified diurnal tension curve and sensors for continuous IOP monitoring have been explored to capture IOP fluctuations over a 24-h span, however none have achieved widespread popularity. 4 Provocative tests have also been developed for the evaluation of patients at high risk for glaucoma. The water drinking test (WDT) is a provocative test that was first described in the early 20th century 5 and was predominantly used in the 1950s and 1960s as a test to detect and diagnose glaucoma.…”

“…Early diagnosis and prompt treatment are important to prevent progression of vision loss. Increased intraocular pressure (IOP) is thought to damage the lamina cribrosa and is considered a major risk factor for glaucoma ( Da Silva and Lira, 2022 ). Elevated IOP currently represents the only modifiable risk factor targeted by therapy for the prevention of glaucoma progression ( Schuster et al, 2020 ; Zukerman et al, 2021 ).…”

Glaucoma is the main cause of irreversible visual loss worldwide, and comprises a group of progressive, age-related, and chronic optic neuropathies. Prostaglandin analogs are considered a first-line treatment in the management of glaucoma and have the best efficacy in reducing intraocular pressure. When comparing these therapeutic agents between them, long-term therapy with 0.03% bimatoprost is the most effective followed by treatment with 0.005% latanoprost and 0.004% travoprost. The prevalence of adverse events is lower for latanoprost than for other prostaglandin analogs. However, some patients do not respond to the treatment with prostaglandin analogs (non-responders). Intraocular pressure-lowering efficacy differs significantly between individuals partly owing to genetic factors. Rs1045642 in ABCB1, rs4241366 in SLCO2A1, rs9503012 in GMDS, rs10306114 in PTGS1, rs11568658 in MRP4, rs10786455 and rs6686438 in PTGFR were reported to be positive with the response to prostaglandin analogs in patients with glaucoma. A negative association was found between single nucleotide polymorphisms of PTGFR (rs11578155 and rs6672484) and the response to prostaglandin analogs in patients with glaucoma. The current review is an analysis of the information relevant to prostaglandin analog treatments based on previous literatures. It describes in detail the clinical pharmacology and pharmacogenetics of drugs belonging to this therapeutical class to provide a sound pharmacological basis for their proper use in ophthalmological clinical practice.
