This study analyses the factors influencing the graft stability after a suture less and glue-free conjunctival autograft in pterygium surgery. Patients and method:A prospective study, all patients underwent pterygium surgery with suture less glue less conjunctival autografting. The parameters studied were: Intraoperative, evaluation of graft stability at the end of the procedure. Postoperative, the graft position on day 1 after surgery.Results: Sixty-four grafts remained stable at the end of the intervention, i.e. 83.12% while 16.88% were unstable. In the postoperative follow-up, 79.22% of grafts were well-positioned including 76.62% of grafts flattened in place and 2.60% of grafts retracted. Grafts displacements were observed in 20.78% of cases including 11.69% of minor displacements and 9.09% of major displacements. One patient had an excessive bleeding, which stopped on day one postoperative. Unstable grafts (84.62%) developed secondary displacements compared to stable grafts (7.81%). The difference was statistically significant, P=002. Out of the 7 cases with major displacement, 5 cases had unstable grafts (6.49%), and 2 cases had stable grafts (2.59%). Conclusion:It is an effective and safe technique with good graft position and stability despite intraoperative surgical adjustments as formerly described in the literature. The absence of postoperative irritation and suture related complications makes it a useful method for graft fixation in pterygium surgery. However, still some improvements are needed for better graft stability.This study presents some technical aspects aimed at improving the graft stability on the first postoperative day. Patients and method PatientsOur study was conducted as part of a decentralized surgical activity in a transportable hospital. The primary target was patients with cataracts, but pterygium also was operated on. Thus 77 eyes of 77 patients were operated from 09-07-2018 to 08-08-2018 Inclusion criteria

Ametropia is one of the leading causes of visual impairment. This study describes epidemiological and clinical aspects of ametropia as part of a free medical care program in Kinkala, Republic of Congo. Patients and Methods: We conducted a cross-sectional study from August 25th to September 24th, 2019; patients presenting complaints suggestive of ametropia were evaluated. The ametropia was determined by the objective method under cyclopentolate eye drops according to the following protocol: 3 applications of one drop every 5 minutes, followed by auto-refractometry at least 45 minutes after the first instillation. The auto-refractometer gave us the objective refraction. An anatomical examination was performed in order to eliminate any organic pathology. Results: Of the 2352 patients received, only 137 patients were included in our survey. Of the 137, 14 were emmetropic. Astigmatism was the most common ametropia. Its axis reversed with age, with more than 65% of direct astigmatism before age 40. There was nearly 65% of reversed astigmatism at 60 years and over. In spherical equivalents, hyperopia accounted for more than 80% of ametropia. Conclusion: Ametropia in Kinkala is dominated by astigmatism. Spherical equivalent, hyperopia represents more than 80% of refractive error.

We evaluated refractive disorders in Albino children of Brazzaville and assessed their impact on the visual acuity of these children.Patients and method: Our study was conducted at the University Hospital of Brazzaville in October 2018 as part of a special program of the Congolese Association of Albinos aimed at providing glasses free of charge to albino children. This was a cross-sectional study of 32 children with oculocutaneous albinism.All children received a complete ophthalmological examination. Ametropia was measured by cycloplegic autorefraction performed approximately 45-60 minutes after topical instillation of 3 drops of 1% cyclopentolate administered 5 minutes apart.Results: All children had nystagmus, including 2 cases with strabismus (6.25%). All children had astigmatism, 56.25% of whom were hypermetropic. The mean corrected visual acuity in the better eye was 0.18+/-0.14. The Mean uncorrected visual acuity in the better eye was 0.33+/-0.15. The improvement in visual acuity after correction was statistically significant P=0.002. Conclusion:Albinism is associated with a variety of ocular anomalies including ametropia. Hypermetropic astigmatism was the most common refractive error identified in our series. Correction of this ametropia results in a statistically significant improvement in visual acuity.

We compared surgically induced astigmatism (SIA) by a superior incision with a temporal incision in manual small incision cataract surgery (MSICS), in patients with bilateral direct (regular) preoperative corneal astigmatisms. Patients and method: We carried out a prospective study from July 1 st 2018 to September 30 th 2019 in the department of ophthalmology at the University Hospital of Brazzaville. Keratometric readings were recorded before surgery to assess preoperative corneal astigmatisms. Keratometric evaluation was done 45 days post-operatively. Patients were followed 90 days after surgery in order to assess the healing of the surgical site. The surgically induced astigmatism (SIA) is the difference in the magnitude vectors between the preoperative and postoperative astigmatism. The result was positive if the postoperative astigmatism was greater than the preoperative astigmatism and negative if the postoperative astigmatism was less than the preoperative astigmatism. Results: Our study sample included 48 eyes from 24 patients, including 24 operated on temporal incision and 24 in superior incision. The average SIA for superior incisions was 0.33 ± 1.55 diopters (D), versus 0.33 ± 1.44 for temporal incisions. For superior incisions the SIA was 0.81 for astigmatisms lower than 2D, against 0.16D for the temporal incisions. On the other hand, for preoperative astigmatisms greater than 2D, the surgically induced astigmatism was −0.62D, marking a decrease in preoperative astigmatism for the superior incisions against an increase of 0.5D for the temporal incisions. The healing was delayed for the temporal incisions responsible for discomfort persisting beyond 45 days. Conclusion: The temporal incision had better re-How to cite this paper:
