| Sažetak | Ciljevi istraživanja: Ispitati postoji li razlika u smanjenju očnog tlaka nakon
fakoemulzifikacije između skupina s obzirom na dubinu prednje očne sobice te utvrditi je li
došlo do promjene proporcije ispitanika s dubokom prednjom očnom sobicom.
Ustroj studije: Kohortno istraživanje
Ispitanici i metode: Istraživanje je obuhvatilo 61 bolesnika, bili su podijeljeni u dvije
skupine, ovisno o ACD-u. Prvu su skupinu činili bolesnici s ACD-om ≤ 2,8 mm, a drugu
skupinu s ACD-om > 2,8 mm. Na dan operacije i mjesec dana nakon zahvata određena je
najbolja korigirana vidna oštrina te vrijednost intraokularnog tlaka. U istome je intervalu
optičkom biometrijom mjerena dubina prednje očne sobice.
Rezultati: Prije zahvata je medijan ACD-a iznosio 2,82 mm, a poslije zahvata su vrijednosti
ACD-a povećane s iznosom medijana 3,18 mm, pri čemu je prije zahvata 32 (53 %) imalo
ACD ≥ 2,8 mm, a poslije zahvata 45 (74 %) ispitanika (McNemar-Bowkerov test, P = 0,001).
Medijan BCVA je značajno poboljšan, s 0,25 na 1,0 (Wilcoxonov test, P < 0,001). Medijan je
IOT-a u skupini s ACD ≥ 2,8 mm prije zahvata iznosio 16,0 mmHg te je ostao iste vrijednosti
i mjesec dana nakon zahvata, dok je u skupini s ACD < 2,8 mm prije zahvata iznosio 16,0
mmHg, a mjesec dana nakon zahvata imao vrijednost 14,0 mmHg, no razlika nije statistički
značajna (Wilcoxonov test, P = 0,05).
Zaključak: Fakoemulzifikacija je dovela do značajnog poboljšanja vidne oštrine te povećanja
ACD-a, povećavajući značajno proporciju ispitanika s dubokom prednjom očnom sobicom.
Smanjenje je intraokularnog tlaka uočeno jedino u skupini s plićom prednjom sobicom, no ta
razlika nije statistički značajna. |
| Sažetak (engleski) | Title: Early Post-Operative Effect of Ultrasound Phacoemulsification Cataract Surgery on
Anterior Chamber Depth and Intraocular Pressure
Aim of the study: To investigate whether there is a difference in intraocular pressure after
ultrasound cataract surgery between the groups with regard to the depth of the anterior
chamber and to determine whether there was a change in the proportion of subjects with a
deep anterior chamber.
Study design: Cohort study
Subjects and methods: The research included 61 patients who underwent
phacoemulsification cataract surgery divided into two groups according to anterior chamber
depth (ACD). The first group consisted of patients with ACD ≤ 2,8 mm, and the second group
with ACD > 2,8 mm. On the day of surgery and one month after the procedure, the best
corrected visual acuity (BCVA) was determined, and intraocular pressure (IOP) was
measured. In the same time interval, the depth of the anterior chamber was measured by
optical biometry.
Results: Before the procedure, the median ACD was 2,82 mm, and after the procedure, the
ACD values increased with a median of 3,18 mm, where before the procedure, 32 (53 %) had
ACD ≥ 2,8 mm, and after the procedure, 45 (74 %) patients (McNemar-Bowker test,
P = 0,001). Median best-corrected visual acuity significantly improved from 0,25 to 1,0
(Wilcoxon test, P < 0,001). The median intraocular pressure in the group with ACD ≥ 2,8 mm
before the procedure was 16,0 mmHg and remained at the same value one month after the
procedure (Wilcoxon test, P = 0,05). In the group with ACD < 2,8 mm, the median intraocular
pressure before the procedure was 16,0 mmHg, and one month after the procedure, it was 14,0
mmHg, but the difference is not statistically significant (Wilcoxon test, P = 0,05).
Conclusion: Phacoemulsification led to a significant improvement in the best corrected visual
acuity and an increase in the depth of the anterior chamber, increasing a significant proportion
of patients with a deep anterior chamber. A decrease in intraocular pressure was observed
only in the group with a preoperative shallower anterior chamber, but this difference was not
statistically significant. |
