Je li tablica ETDRS bolja od Snellenove tablice u procjeni vidne oŔtrine kod operacije katarakte?
This study was designed to explore practical differences between visual acuity (VA)
scores measured on Snellen chart versus ETDRS chart, to grade cataracts using LOCS III system, and
to compare VA on both charts depending on cataract grade and type. Prospective evaluation of uncorrected
and best-corrected visual acuity was carried out on the eye scheduled for cataract surgery preoperatively
and postoperatively on the Snellen and ETDRS charts. The study was carried out at Department
of Eye Diseases, Clinical Center of Serbia, during a two-year period. Inclusion criteria were
met by 540 patients who underwent testing, surgery, data collection and analysis. The mean VA score
was better on ETDRS than on Snellen chart. The mean difference was 6.05 letters or 1.21 lines. VA
results correlated with all types of cataract regardless of the chart used, with the highest statistical
significance (p<0.0001) for subcapsular cataract. The ETDRS chart was found to be more discriminative
and precise than Snellen chart, especially for poor VA.Cilj studije bio je procijeniti razlike vidne oŔtrine mjerene Snellenovom tablicom nasuprot tablici ETDRS, odrediti stupanj
katarakte primjenom sustava LOCS III i usporediti vidnu oÅ”trinu dobivenu pomoÄu oba optotipa ovisno o tipu i stupnju
katarakte. Provedena je prospektivna procjena nekorigirane i najbolje korigirane vidne oŔtrine primjenom tablica Snellen
i ETDRS prije i nakon operacije katarakte. Ova dvogodiÅ”nja studija izvedena je na Klinici za oÄne bolesti KliniÄkog centra
Srbije. Kriterije za ukljuÄivanje u studiju ispunilo je 540 bolesnika koji su podvrgnuti testiranju, operaciji, prikupljanju i analizi
podataka. Srednja vrijednost zbroja vidne oŔtrine procijenjena tablicom ETDRS bila je bolja u usporedbi sa Snellenovom
tablicom. Srednja vrijednost bila je 6,05 slova ili 1,21 linija. Rezultati vidne oŔtrine korelirali su sa svim tipovima katarakte
bez obzira na tablicu koja se primijenila, s najveÄom statistiÄkom znaÄajnoÅ”Äu (p<0,0001) za subkapsularnu kataraktu. Grafikon
ETDRS pokazao se viŔe diskriminativnim i preciznijim nego Snellenov, osobito za slabu vidnu oŔtrinu
DijagnostiÄka vrednost tri jednostavna i brza testa za suvo oko ā nabori konjunktive paralelni ivici kapka, visina meniskusa suza i test grananja suza
Introduction/Objective The objective of this paper was to assess the diagnostic value of three simple dry eye (DE) tests: lid parallel conjunctival folds (LIPCOF), tear meniscus height (TMH), and tear ferning (TF). Methods LIPCOF, TMH, and TF diagnostic DE tests were performed in 100 patients. Eighty of them were referred to us by rheumatologists and general practitioners either during evaluation for Sjƶgrenās syndrome, or because of DE symptoms. The control group was composed of 20 patients, with no DE-related symptoms. Ocular Surface Disease Index questionnaire was used for DE symptomsā evaluation. Results of LIPCOF, TMH, and TF tests were compared with results of the Copenhagen criteria DE tests i.e., tear fluorescein breakup time, Schirmer I and Rose Bengal tests. Ability of the tests to recognize DE in various grades according to Dry Eye Work Shop (DEWS) report score system was assessed. Results Compared to the Copenhagen criteria, sensitivity of LIPCOF and TMH was high (92.8% and 83.5%, respectively), while specificity was low (34.4% and 49.2%, respectively). TF had low sensitivity (59.1%) but high specificity (82.7%). Mean values of both LIPCOF and TMH differed significantly (F = 7.222, p < 0.001 and F = 11.802, p < 0.001, respectively) between the control group and all DEWS grades, but not among different grades of DE. Conclusion TMH and LIPCOF diagnostic tests showed high sensitivity, which makes them excellent screening DE tests. Low sensitivity of TF suggests that it is not truly a good screening test on its own, but its high specificity is of definite value.Uvod/Cilj Cilj ovog rada je da se proceni dijagnostiÄka vrednost tri jednostavna testa za suvo oko: nabori konjunk- tive paralelni ivici kapka (NKPIK), visina meniskusa suza (VMS) i test grananja suze (GS). Metode DijagnostiÄki testovi NKPIK, VMS i GS su izvedeni kod 100 pacijenata, od kojih nam je 80 upuÄeno na pregled od strane reumatologa i nadležnih oftalmologa, tokom ispitivanja na Sjogrenov sindrom ili zbog simptoma suvog oka. Kontrolnu grupu je Äinilo 20 pacijenata bez simptoma suvog oka. Simptomi su evaluirani primenom upitnika o indeksu bolesti povrÅ”ine oka. Rezultati testova NKPIK, VMS i GS su uporeÄeni sa vrednostima rezultata testova za suvo oko po KopenhaÅ”kim kriterijumima, a to su: vreme prekida suznog filma obojenog fluoresceinom, merenje sekrecije suza bez anestezije tokom pet minuta Å imero- vom trakom (Schirmer I) i bojenje povrÅ”ine oka vitalnom bojom Rose Bengal. TakoÄe je procenjena sposobnost testova da prepoznaju razliÄite stadijume po sistemu gradiranja bolesti Dry Eye Work Shop (DEWS). Rezultati PoreÄenjem sa grupom testova po KopenhaÅ”kim kriterijumima, NKPIK i VMS su pokazali visoku senzitiv- nost (92,8% i 83,5%), dok im je specifiÄnost bila niska (34,4% i 49,2%). GS je imao nisku senzitivnost (59,1%), ali visoku specifiÄnost (82,7%). ProseÄne vrednosti testova NKPIK i VMS se statistiÄki znaÄajno razlikuju izmeÄu kon- trolne grupe i svih stadijuma bolesti po gradaciji DEWS, ali ne i izmeÄu razliÄitih stadijuma bolesti suvog oka. ZakljuÄak Testovi VMS i NKPIK su pokazali visoku senzi- tivnost, Å”to ih Äini odliÄnim testovima za skrining bole- sti suvog oka. Niska senzitivnost testa GS ga ne svrstava u dobre skrining testove, ali njegova visoka specifiÄnost mu daje dijagnostiÄku vrednost.This paper is a part of a doctoral thesis: DaÄiÄ-Krnjaja B.

Argon-plasma coagulation as a primary therapeutic method for the treatment of flat duodenal adenomas
Background. Argon-plasma coagulation is a method for tissue coagulation that uses high-frequency electric energy and ionized argon gas. It is used in endoscopic haemostasis and in coagulation of smaller, superficial lesion on gastrointestinal mucosa such as flat adenomas, but also in reduction of tumor tissue. Case report. We presented a patient with flat adenoma duodeni. Adenoma had been treated with argon plasma coagulation, in one act, and with a complete restitution of mucosa in further follows up. Conclusion. Argon plasma can be efficiently used in coagulation of superficial lesion of gastrointestinal mucosa, that belongs to the type of flat adenomas, as well as other superficial lesions of mucosa that require endoscopic mucosectomy from smaller, bordered spaces
