Ocular Complications in Diabetic Patients: Prevalence, Impact on Quality of Life, and Implications for Healthcare

Introduction: Diabetes, a chronic disease characterized by persistent hyperglycemia, poses a major global health challenge. In Gabon, 10% of the population is affected by this condition, highlighting the need to actively understand and manage it. Ocular complications of diabetes, including diabetic retinopathy, glaucoma, and cataracts, have a devastating impact on patients quality of life and represent a crucial issue for healthcare systems. Methodology: This study conducted in Libreville from February 9, 2022, to April 15, 2022, was cross-sectional, longitudinal, and descriptive, with prospective data collection. Participants were diabetic patients regularly followed in the endocrinology department of CHUL, who were referred for a comprehensive ophthalmological examination at CHUO. Sampling was exhaustive, with strict inclusion criteria aimed at ensuring the representativeness of the study population. Results: The mean age of participants was 57.5 ± 13.2 years with a male-to-female ratio of 0.8. Personal histories were dominated by hypertension, while family histories were dominated by diabetes. Ocular complications of diabetes included refractive disorders (78.9%), cataracts (31.7%), glaucoma (78.9%), and diabetic retinopathy (13.7%). These ocular complications had a significant impact on participants’ quality of life, leading to impaired vision (78.9%), difficulties in carrying out daily activities (62.2%), the need for caregiver assistance (50.3%), high levels of stress and anxiety (68.9%), regular medication intake (71.4%), adherence to a specific diet (55.9%), and frequent blood glucose monitoring (74.5%). Conclusion: This study highlights the major impact of diabetic ocular complications on patients’ quality of life.

The impact of combined oral contraceptives on ocular tissues:a review of ocular effects

The aim of this manuscript is to review the action and adverse effects of combined oral contraceptives（COCs）on ocular tissues.The percentage of unwanted pregnancies and the subsequent abortions make contraception crucial worldwide.Over 100 million women around the world use common contraceptive methods,including intrauterine devices,combined estrogen and progestin oral contraceptives,as well as progestin only preparations（oral contraceptives,implants or injections）.COCs are widely used for contraception,but they are also indicated in menorrhagia,endometriosis,acne and hirsutism,fibroid uterus and premenstrual syndrome.However,they have been associated with high rates of cardiovascular events,venous thromboembolic disease,ischemic strokes and breast cancer.The incidence of COCs-related ocular complications is estimated to be 1 in 230 000,including dry eye symptoms,corneal edema,lens opacities and retinal neuro-ophthalmologic or vascular complications.We may infer that the serious ocular complications of COCs can be prevented by eliminating the estrogen dosage and choosing third-generation progestins.In any case,doctors should take into consideration the systemic and ocular history of the patients before selecting any method of contraception.

Determinants of the Ophthalmological Follow-Up of Sickle Cell Patients at the National Center of Research and Care for Sickle Cell Patients in Lome-Togo

Objectives: To assess the factors influencing the ophthalmological follow-up of sickle cell patients in Togo. Materials and Methods: The national center of research and care for sickle cell patients (CNRSD) served as study setting. It was a descriptive and analytical study by interview over a three-month period from December 01, 2020 to March 02, 2021. Was included in the study, any patient with sickle cell disease genotype SS or SC, age ≥ 17 years, regularly followed at the CNRSD and having accepted the interview by a survey sheet. Excluded were patients with sickle cell trait genotype AS or AC or with a disability that prevented them from being interviewed. Results: Two hundred and fifty (250) patients with sickle cell disease were interviewed. The mean age was 29.1 years ± 11.12 years [17 years;67 years] and the sex ratio = 0.52. Nine patients over ten (9/10) attended at least secondary school. The jobless represented 25.60% of the total population followed respectively by students and laborers in 20.40% and 16% of cases. Twenty-four percent (24%) of patients were followed up in ophthalmology department. Statistically, there was no significant relationship between level of education (p = 0.4083), occupation (p = 0.6441) and knowledge of the ocular complications of sickle cell disease. Statistically, there was a significant relationship between knowledge of the ocular complications of sickle cell disease and compliance with ophthalmological follow-up (p = 0.0009). Conclusion: The knowledge of eye disorders related to sickle cell disease by patients with sickle cell disease improves their ophthalmological follow-up. Greater awareness on eye disorders related to sickle cell disease by medical staff towards patients with sickle cell disease would improve ophthalmological follow-up. .

Ophthalmic manifestations in patients with inflammatory bowel disease: a review

Clinical manifestations of inflammatory bowel disease(IBD) are not locally restricted to the gastrointestinal tract, and a significant portion of patients have involvement of other organs and systems. The visual system is one of the most frequently affected, mainly by inflammatory disorders such as episcleritis, uveitis and scleritis. A critical review of available literature concerning ocular involvement in IBD, as it appears in Pub Med, was performed. Episcleritis, the most common ocular extraintestinal manifestation(EIM), seems to be more associated with IBD activity when compared with other ocular EIMs. In IBD patients, anterior uveitis has an insidious onset, it is longstanding and bilateral, and not related to the intestinal disease activity. Systemic steroids or immunosuppressants may be necessary in severe ocular inflammation cases, and control of the underlying bowel disease is important to prevent recurrence. Our review revealed that ocular involvement is more prevalent in Crohn's disease than ulcerative colitis, in active IBD, mainly in the presence of other EIMs. The ophthalmic symptoms in IBD are mainly nonspecific and their relevance may not be recognized by the clinician; most ophthalmic manifestations are treatable, and resolve without sequel upon prompt treatment. A collaborative clinical care team for management of IBD that includes ophthalmologists is central for improvement of quality care for these patients, and it is also cost-effective.
