Objective

To carry out a methodologically complete validation of the Spanish version of the Keratoconus End-Points Assessment Questionnaire (KEPAQ) in a Spanish population with keratoconus.

Method

Analytical, prospective study, including patients with keratoconus without previous surgical history, in which a measurement of quality of life was performed using the KEPAQ questionnaire, a complete exploration of the anterior pole and a corneal elevation topography with the Galilei™ G6 topographer. The evaluation of the psychometric characteristics of the scale in the studied population was carried out using Rasch modeling.

Results

A total of 140 patients with keratoconus were included, with a median age of 26.0 years, the majority (57.6%) being men. For the KEPAQ-E subscale, the median score was 69.3, with a reliability of 0.85 and an eigenvalue of the first contrast of 2.34. For the KEPAQ-F, the median score was 56.4, with a reliability of 0.88 and an eigenvalue of 2.00. All infit and outfit parameters were within normal limits for both subscales. A significant evaluation was found between the evaluations of both subscales (rho = 0.696; p < 0.001). The evaluations of the subscales and various clinical and tomographic characteristics showed a significant classification between them (p value between 0.048 y 0.001).

Conclusion

The KEPAQ is a psychometrically robust and valid scale to evaluate quality of life in the Spanish population with keratoconus. This questionnaire can be easily used for both clinical and research aims.

Background

Benign essential blepharospasm is the most common adult-onset focal facial dystonia and its treatment of choice is periodic application of botulinum toxin (BtA). It has a higher incidence in middle and late adulthood, especially in women between 40 and 60 years of age.

Objective

To carry out the translation and cross-cultural adaptation of the CDQ24 questionnaire in its Spanish version in patients diagnosed with benign essential blepharospasm who have been treated with BtA in an ophthalmologic center in Bogotá - Colombia.

Materials and methods

Pilot test of validation study and adaptation of a scale assembled in a prospective cohort of the CDQ24 instrument to Spanish in adult patients with primary blepharospasm treated with botulinum toxin in Bogota, Colombia.

Results

We obtained a sample of 26 patients to whom the instrument was applied after translation and retranslation of the original document, composed of 19 (73%) women with a median age of 64.5 years; the average time to answer the survey was 4.93 minutes. The internal consistency of the scale evaluated by Cronbach's Alpha had a total score of 0.78. Criterion validity between the CDQ24 scale and the WHOQOL-BREF quality of life scale was determined by determining correlation between the Emotional Well-Being and Phsychological domains of both scales.

Conclusions

The translation and cross-cultural adaptation of the CDQ-24 scale into Spanish allowed the applicability of the instrument to the Spanish-speaking population during the pilot test, which allows us to continue the relevant studies in the study population.

The aim of this article is to report clinical features and therapeutic approach of cicatrizing keratoconjunctivitis secondary to ocular lichen planus based on a case report. The patient is a 77-year-old female with a history of ocular discomfort and recurrent keratoconjunctivitis that did not improve with conservative treatment, as well as a history of oral and nasal aphthous ulcers. After a complete ophthalmologic, dermatologic and anatomopathological study, the diagnosis of ocular lichen planus was established and immunosuppressive treatment was initiated.

Most cases of ocular lichen planus are presented as chronic cicatricial conjunctivitis. A correct differential diagnosis, as well as an early detection are essential for the control of this entity and its sequelae. Treatment, based on corticosteroids and immunosuppressants, both topical and systemic, is aimed at controlling inflammation and scarring.

To report a unique case of a patient who developed simultaneous bilateral maculopathy presumed from intake of fluoxetine. The optic coherence tomography (OCT) macular showed a subfoveal disruption in the outer retinal layer in both eyes (OU), higher in the left one (OS). Although reported cases of serotonin recapture inhibitors (SSRIs) Maculopathy so far have been caused by sertraline, fluoxetine shares the biological mechanism, and OCT findings and ocular symptoms are the same as published. We should be aware with ocular symptoms in patients that take fluoxetine.

Objective

To study the clinical characteristics of macular diplopia, treatment, and outcome.

Methods

Retrospective descriptive study of cases referred to the ocular motility section of a tertiary hospital with diplopia, diagnosed with macular diplopia between 2022-23. The etiology of the macular pathology and the type of associated strabismus were recorded. The result was considered good if the diplopia improved or was eliminated with the medical or surgical treatment. Follow-up time from the onset of diplopia until data collection was recorded.

Results

A total of 19 cases comprised the sample (63.2% women), mean age: 67.16 years. Amblyopia (21.1%), high myopia (47.4%), epirretinal membrane (ERM) (36.8%), neovascular membrane (26.3%), macular hole (10.5%), and lamellar (15.8%), and age macular degeneration (5.3%) were registered. The 47.4% had vertical diplopia, horizontal: 5.3 and 47.4% mixed. The mean horizontal deviation was: 7.3 PD (prism diopters) and vertical: 6.22 PD. Ocular extorsion was observed in 26.3%, and intorsion: 5.3%. Torticollis was present in 15.8%. The treatment consisted of strabismus surgery + Botox (15.8%), strabismus surgery (47.4%), medical treatment with Fresnel prims or Scotch cellophane (36.8%). A 68.4% presented a good result at the end of the study. The mean follow-up was 55.58 months.

Conclusions

Misregistration of macular photoreceptors is the most common cause of binocular diplopia in patients with ERM or other macular pathologies. Most complains of vertical or mixed diplopia. Sensorimotor evaluation of these patients should be thorough. Early diagnosis prevents unnecessary prescription of prism glasses. Surgical and/or medical treatment achieves good results in most cases.

The limited accessibility to ophthalmological services in remote regions of developing countries poses a significant challenge in visual healthcare. Cataracts and refractive errors are prominent causes of visual impairment, and surgery, despite being an efficient option, faces barriers in developing countries due to financial and geographical constraints. Humanitarian missions play a vital role in addressing this issue. The improvement in the accuracy of calculating IOL power through techniques such as keratometry and biometry is a fundamental step towards optimizing surgical outcomes and the quality of life for patients in these underserved regions. In this context, the consideration of keratometry and immersion ultrasound biometry as preoperative assessment standards in cataract surgeries in developing countries is presented as a pertinent and advisable strategy.

Background and objective

To describe visual function, macular integrity, and fixation stability using (macular integrity assessment) microperimetry (MAIA) after retinal detachment surgery. Evaluate if there are statistically significant differences between surgical approaches.

Materials and methods

A prospective, comparative, interventional study was conducted, recruiting a total of 21 patients with rhegmatogenous retinal detachment and macula-off. Eleven patients underwent surgery using pars plana vitrectomy, and 10 patients underwent scleral buckle surgery. Clinical examinations and optical coherence tomography were performed post-surgery. MAIA microperimetry was conducted at 6 months.

Results

Best-corrected visual acuity (BCVA) and the number of letters read improved over time in the operated eye but did not reach the level of the control eye (P = 0.001). No significant differences were found between the 2 surgical approaches in BCVA (P = 0.230) or the number of letters read (P = 0.608). Macular integrity in the operated eye did not match that of the control eye in both procedures (P = 0.05). No differences were detected between the 2 surgeries, either in macular integrity (P = 0.512) or fixation stability (P = 0.835).

Conclusions

Following retinal detachment surgery, a decrease in BCVA and the number of letters read occurs, which does not reach the level of the control eye. No significant differences were observed between the 2 surgical approaches. Macular integrity in the operated eye does not match that of the control eye.
